Lymph vessels: A network of thin tubes that collect lymph from different parts of the body and return it to the bloodstream.
Lymph nodes: Small, bean-shaped structures that filter lymph and store white blood cells that help fight infection and disease. Lymph nodes are found along a network of lymph vessels throughout the body. Groups of lymph nodes are found in the neck, underarm, mediastinum, abdomen, pelvis, and groin.
Spleen: An organ that makes lymphocytes, stores red blood cells and lymphocytes, filters the blood, and destroys old blood cells. The spleen is on the left side of the abdomen near the stomach.
Thymus: An organ in which T lymphocytes mature and multiply. The thymus is in the chest behind the breastbone.
Tonsils: Two small masses of lymph tissue at the back of the throat. There is one tonsil on each side of the throat.
Bone marrow: The soft, spongy tissue in the center of certain bones, such as the hip bone and breastbone. White blood cells, red blood cells, and platelets are made in the bone marrow.
EnlargeAnatomy of the lymph system, showing the lymph vessels and lymph organs including lymph nodes, tonsils, thymus, spleen, and bone marrow. Lymph (clear fluid) and lymphocytes travel through the lymph vessels and into the lymph nodes where the lymphocytes destroy harmful substances. The lymph enters the blood through a large vein near the heart.
Lymph tissue is also found in other parts of the body such as the lining of the digestive tract, bronchus, and skin.
There are two general types of lymphomas: Hodgkin lymphoma and non-Hodgkin lymphoma. This summary is about the treatment of non-Hodgkin lymphoma in adults, including during pregnancy.
Non-Hodgkin lymphoma can be indolent or aggressive.
Non-Hodgkin lymphoma grows and spreads at different rates and can be indolent or aggressive. Indolent lymphoma tends to grow and spread slowly, and has few signs and symptoms. Aggressive lymphoma grows and spreads quickly, and has signs and symptoms that can be severe. The treatments for indolent and aggressive lymphoma are different.
This summary is about the following types of non-Hodgkin lymphoma:
Indolent non-Hodgkin lymphomas
Follicular lymphoma. Follicular lymphoma is the most common type of indolent non-Hodgkin lymphoma. It is a very slow-growing type of non-Hodgkin lymphoma that begins in B lymphocytes. It affects the lymph nodes and may spread to the bone marrow or spleen. Most patients with follicular lymphoma are age 50 years and older when they are diagnosed. Follicular lymphoma may go away without treatment. The patient is closely watched for signs or symptoms that the disease has come back. Treatment is needed if signs or symptoms occur after the cancer disappeared or after initial cancer treatment. Sometimes follicular lymphoma can become a more aggressive type of lymphoma, such as diffuse large B-cell lymphoma.
Lymphoplasmacytic lymphoma. In most cases of lymphoplasmacytic lymphoma, B lymphocytes that are turning into plasma cells make large amounts of a protein called monoclonalimmunoglobulin M (IgM) antibody. High levels of IgM antibody in the blood cause the blood plasma to thicken. This may cause signs or symptoms such as trouble seeing or hearing, heart problems, shortness of breath, headache, dizziness, and numbness or tingling of the hands and feet. Sometimes there are no signs or symptoms of lymphoplasmacytic lymphoma. It may be found when a blood test is done for another reason. Lymphoplasmacytic lymphoma often spreads to the bone marrow, lymph nodes, and spleen. Patients with lymphoplasmacytic lymphoma should be checked for hepatitis C virus infection. It is also called Waldenström macroglobulinemia.
Marginal zone lymphoma. This type of non-Hodgkin lymphoma begins in B lymphocytes in a part of lymph tissue called the marginal zone. The prognosis may be worse for patients aged 70 years or older, those with stage III or stage IV disease, and those with high lactate dehydrogenase (LDH) levels. There are five different types of marginal zone lymphoma. They are grouped by the type of tissue where the lymphoma formed:
Nodal marginal zone lymphoma. Nodal marginal zone lymphoma forms in lymph nodes. This type of non-Hodgkin lymphoma is rare. It is also called monocytoid B-cell lymphoma.
Extragastric MALT lymphoma. Extragastric MALT lymphoma begins outside of the stomach in almost every part of the body including other parts of the gastrointestinal tract, salivary glands, thyroid, lung, skin, and around the eye. This type of marginal zone lymphoma forms in cells in the mucosa that help make antibodies. Extragastric MALT lymphoma may come back many years after treatment.
Mediterranean abdominal lymphoma. This is a type of MALT lymphoma that occurs in young adults in eastern Mediterranean countries. It often forms in the abdomen and patients may also be infected with bacteria called Campylobacter jejuni. This type of lymphoma is also called immunoproliferative small intestinal disease.
Splenic marginal zone lymphoma. This type of marginal zone lymphoma begins in the spleen and may spread to the peripheral blood and bone marrow. The most common sign of this type of splenic marginal zone lymphoma is a spleen that is larger than normal.
Primarycutaneousanaplastic large cell lymphoma. This type of non-Hodgkin lymphoma is in the skin only. It can be a benign (not cancer) nodule that may go away on its own or it can spread to many places on the skin and need treatment.
Aggressive non-Hodgkin lymphomas
Diffuse large B-cell lymphoma. Diffuse large B-cell lymphoma is the most common type of non-Hodgkin lymphoma. It grows quickly in the lymph nodes and often the spleen, liver, bone marrow, or other organs are also affected. Signs and symptoms of diffuse large B-cell lymphoma may include fever, drenching night sweats, and weight loss. These are also called B symptoms.
Primary mediastinal large B-cell lymphoma. This type of non-Hodgkin lymphoma is a type of diffuse large B-cell lymphoma. It is marked by the overgrowth of fibrous (scar-like) lymph tissue. A tumor most often forms behind the breastbone. It may press on the airways and cause coughing and trouble breathing. Most patients with primary mediastinal large B-cell lymphoma are women who are age 30 to 40 years.
Follicular large cell lymphoma, stage III. Follicular large cell lymphoma, stage III, is a very rare type of non-Hodgkin lymphoma. Treatment of this type of follicular lymphoma is more like treatment of aggressive NHL than of indolent NHL.
Anaplastic large cell lymphoma. Anaplastic large cell lymphoma is a type of non-Hodgkin lymphoma that usually begins in T lymphocytes. The cancer cells also have a marker called CD30 on the surface of the cell.
There are two types of anaplastic large cell lymphoma:
Cutaneous anaplastic large cell lymphoma. This type of anaplastic large cell lymphoma mostly affects the skin, but other parts of the body may also be affected. Signs of cutaneous anaplastic large cell lymphoma include one or more bumps or ulcers on the skin. This type of lymphoma is rare and indolent.
Systemic anaplastic large cell lymphoma. This type of anaplastic large cell lymphoma begins in the lymph nodes and may affect other parts of the body. This type of lymphoma is more aggressive. Patients may have a lot of anaplastic lymphoma kinase (ALK) protein inside the lymphoma cells. These patients have a better prognosis than patients who do not have extra ALK protein. Systemic anaplastic large cell lymphoma is more common in children than adults. For more information, see Childhood Non-Hodgkin Lymphoma Treatment.
ExtranodalNK-/T-cell lymphoma. Extranodal NK-/T-cell lymphoma usually begins in the area around the nose. It may also affect the paranasal sinus (hollow spaces in the bones around the nose), roof of the mouth, trachea, skin, stomach, and intestines. Most cases of extranodal NK-/T-cell lymphoma have Epstein-Barr virus in the tumor cells. Sometimes hemophagocytic syndrome occurs (a serious condition in which there are too many active histiocytes and T cells that cause severe inflammation in the body). Treatment to suppress the immune system is needed. This type of non-Hodgkin lymphoma is not common in the United States.
Angioimmunoblastic T-cell lymphoma. This type of non-Hodgkin lymphoma begins in T cells. Swollen lymph nodes are a common sign. Other signs may include a skin rash, fever, weight loss, or drenching night sweats. There may also be high levels of gamma globulin (antibodies) in the blood. Patients may also have opportunistic infections because their immune systems are weakened.
Peripheral T-cell lymphoma. Peripheral T-cell lymphoma begins in mature T lymphocytes. This type of T lymphocyte matures in the thymus gland and travels to other lymphatic sites in the body such as the lymph nodes, bone marrow, and spleen. There are three subtypes of peripheral T-cell lymphoma:
Hepatosplenic T-cell lymphoma. This is an uncommon type of peripheral T-cell lymphoma that occurs mostly in young men. It begins in the liver and spleen and the cancer cells also have a T-cell receptor called gamma/delta on the surface of the cell.
Subcutaneous panniculitis-like T-cell lymphoma. Subcutaneous panniculitis-like T-cell lymphoma begins in the skin or mucosa. It may occur with hemophagocytic syndrome (a serious condition in which there are too many active histiocytes and T cells that cause severe inflammation in the body). Treatment to suppress the immune system is needed.
Enteropathy-type intestinal T-cell lymphoma. This type of peripheral T-cell lymphoma occurs in the small bowel of patients with untreated celiac disease (an immune response to gluten that causes malnutrition). Patients who are diagnosed with celiac disease in childhood and stay on a gluten-free diet rarely develop enteropathy-type intestinal T-cell lymphoma.
Intravascular large B-cell lymphoma. This type of non-Hodgkin lymphoma affects blood vessels, especially the small blood vessels in the brain, kidney, lung, and skin. Signs and symptoms of intravascular large B-cell lymphoma are caused by blocked blood vessels. It is also called intravascular lymphomatosis.
Burkitt lymphoma. Burkitt lymphoma is a type of B-cell non-Hodgkin lymphoma that grows and spreads very quickly. It may affect the jaw, bones of the face, bowel, kidneys, ovaries, or other organs. There are three main types of Burkitt lymphoma (endemic, sporadic, and immunodeficiency related). Endemic Burkitt lymphoma commonly occurs in Africa and is linked to the Epstein-Barr virus, and sporadic Burkitt lymphoma occurs throughout the world. Immunodeficiency-related Burkitt lymphoma is most often seen in patients who have AIDS. Burkitt lymphoma may spread to the brain and spinal cord and treatment to prevent its spread may be given. Burkitt lymphoma occurs most often in children and young adults. For more information, see Childhood Non-Hodgkin Lymphoma Treatment. Burkitt lymphoma is also called diffuse small noncleaved-cell lymphoma.
Lymphoblastic lymphoma. Lymphoblastic lymphoma may begin in T cells or B cells, but it usually begins in T cells. In this type of non-Hodgkin lymphoma, there are too many lymphoblasts (immature white blood cells) in the lymph nodes and the thymus gland. These lymphoblasts may spread to other places in the body, such as the bone marrow, brain, and spinal cord. Lymphoblastic lymphoma is most common in teenagers and young adults. It is a lot like acute lymphoblastic leukemia (lymphoblasts are mostly found in the bone marrow and blood). For more information, see Adult Acute Lymphoblastic Leukemia Treatment.
Mantle cell lymphoma. Mantle cell lymphoma is a type of B-cell non-Hodgkin lymphoma that usually occurs in middle-aged or older adults. It begins in the lymph nodes and spreads to the spleen, bone marrow, blood, and sometimes the esophagus, stomach, and intestines. Patients with mantle cell lymphoma have too much of a protein called cyclin-D1 or a certain gene change in the lymphoma cells. In some patients who do not have signs or symptoms of lymphoma, delaying the start of treatment does not affect the prognosis.
True histiocytic lymphoma. This is a rare, very aggressive type of lymphoma. It is not known whether it begins in B cells or T cells. It does not respond well to treatment with standard chemotherapy.
Primary effusion lymphoma. Primary effusion lymphoma begins in B cells that are found in an area where there is a large build-up of fluid, such as the areas between the lining of the lung and chest wall (pleural effusion), the sac around the heart and the heart (pericardial effusion), or in the abdominal cavity. There is usually no tumor that can be seen. This type of lymphoma often occurs in patients who are infected with HIV.
Plasmablastic lymphoma. Plasmablastic lymphoma is a type of large B-cell non-Hodgkin lymphoma that is very aggressive. It is most often seen in patients with HIV infection.
Older age, being male, and having a weakened immune system can increase the risk of
non-Hodgkin lymphoma.
Anything that increases a person's chance of getting a disease is called a risk factor. Not every person with one or more of these risk factors will develop non-Hodgkin lymphoma, and it can develop in people who don't have any known risk factors. Talk with your doctor if you think you may be at risk.
These and other risk factors may increase the risk of certain types of non-Hodgkin lymphoma:
Being older, male, or White.
Having one of the following medical conditions that weakens the immune system:
Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following:
The number of red blood cells, white blood cells, and platelets.
The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.
The portion of the sample made up of red blood cells.
EnlargeComplete blood count (CBC). Blood is collected by inserting a needle into a vein and allowing the blood to flow into a tube. The blood sample is sent to the laboratory and the red blood cells, white blood cells, and platelets are counted. The CBC is used to test for, diagnose, and monitor many different conditions.
Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by
organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign
of disease.
LDH test: A procedure in which a blood sample is checked to measure the amount of lactic dehydrogenase. An increased amount of LDH in the blood may be a sign of tissue damage, lymphoma, or other diseases.
Hepatitis B and hepatitis C test: A procedure in which a sample of blood is checked to measure the amounts of hepatitis B virus-specific antigens and/or antibodies and the amounts of hepatitis C virus-specific antibodies. These antigens or antibodies are called markers. Different markers or combinations of markers are used to determine whether a patient has a hepatitis B or C infection, has had a prior infection or vaccination, or is susceptible to infection. Patients who have been treated for hepatitis B virus in the past need continued monitoring to check if it has reactivated. Knowing whether a person has hepatitis B or C may help plan treatment.
HIV test: A test to measure the level of HIV antibodies in a sample of blood. Antibodies are made by the body when it is invaded by a foreign substance. A high level of HIV antibodies may mean the body has been infected with HIV.
CT scan (CAT scan):
A procedure that makes a series of detailed pictures of areas inside the body, such as the neck, chest, abdomen, pelvis, and lymph nodes, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
PET scan (positron
emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactiveglucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
Bone marrow aspiration and biopsy: The removal of bone marrow and a small piece of bone by inserting a needle into the hipbone or breastbone. A pathologist views the bone marrow and bone under a microscope to look for signs of cancer.EnlargeBone marrow aspiration and biopsy. After a small area of skin is numbed, a bone marrow needle is inserted into the patient’s hip bone. Samples of blood, bone, and bone marrow are removed for examination under a microscope.
Lymph node biopsy: The
removal of all or part of a lymph node. A pathologist views the tissue under a microscope to check for cancer cells. One of the following types of biopsies may be done:
Core biopsy: The removal of part of a lymph node using a wide needle.
If cancer is found, the following tests may be done to study the cancer cells:
Immunohistochemistry: A laboratory test that uses antibodies to check for certain antigens (markers) in a sample of a patient’s tissue. The antibodies are usually linked to an enzyme or a fluorescent dye. After the antibodies bind to a specific antigen in the tissue sample, the enzyme or dye is activated, and the antigen can then be seen under a microscope. This type of test is used to help diagnose cancer and to help tell one type of cancer from another type of cancer.
Cytogenetic analysis: A laboratory test in which the chromosomes of cells in a sample of blood or bone marrow are counted and checked for any changes, such as broken, missing, rearranged, or extra chromosomes. Changes in certain chromosomes may be a sign of cancer. Cytogenetic analysis is used to help diagnose cancer, plan treatment, or find out how well treatment is working.
Immunophenotyping: A laboratory test that uses antibodies to identify cancer cells based on the types of antigens or markers on the surface of the cells. This test is used to help diagnose specific types of lymphoma.
FISH (fluorescence in situ hybridization): A laboratory test used to look at and count genes or chromosomes in cells and tissues. Pieces of DNA that contain fluorescent dyes are made in the laboratory and added to a sample of a patient’s cells or tissues. When these dyed pieces of DNA attach to certain genes or areas of chromosomes in the sample, they light up when viewed under a fluorescent microscope. The FISH test is used to help diagnose cancer and help plan treatment.
Other tests and procedures may be done depending on the signs and symptoms seen and where the cancer forms in the body.
Certain factors affect prognosis (chance
of recovery) and treatment options.
The prognosis and treatment options depend on the following:
The patient's signs and symptoms, including whether or not they have B symptoms (fever for no known reason, weight loss for no known reason, or drenching night sweats).
The stage of the cancer (the size of the cancer tumors and whether the cancer has spread to other parts of the body or lymph nodes).
The type of non-Hodgkin lymphoma.
The amount of lactate dehydrogenase (LDH) in the blood.
Whether there are certain changes in the genes.
The patient’s age, sex, and
general health.
Whether the lymphoma is newly diagnosed, continues to grow during treatment, or has recurred (come back).
For non-Hodgkin lymphoma during pregnancy, treatment options also depend on:
The wishes of the patient.
Which trimester of pregnancy the patient is in.
Whether the baby can be delivered early.
Some types of non-Hodgkin lymphoma spread more quickly than
others do. Most non-Hodgkin lymphomas that occur during pregnancy are
aggressive. Delaying treatment
of aggressive lymphoma until after the baby is born may lessen the mother's chance of survival. Immediate
treatment is often recommended, even during pregnancy.
Stages of Non-Hodgkin Lymphoma
Key Points
After non-Hodgkin lymphoma has been diagnosed, tests are done to find out
whether cancer cells have spread within the lymph
system or to other parts of the body.
There are three ways that cancer spreads in the body.
The following stages are used for non-Hodgkin
lymphoma:
Stage I
Stage II
Stage III
Stage IV
Non-Hodgkin lymphomas may be grouped for treatment according to whether the cancer is indolent or aggressive, whether affected lymph nodes are next to each other in the body, and whether the cancer is newly diagnosed or recurrent.
Non-Hodgkin lymphoma can recur (come back) after it has been treated.
After non-Hodgkin lymphoma has been diagnosed, tests are done to find out
whether cancer cells have spread within the lymph
system or to other parts of the body.
The process used to find out the type of cancer and if cancer cells
have spread within the lymph system or to other parts of the body is called staging. The
information gathered from the staging process determines the stage of the
disease. It is important to know the stage of the disease in order to plan treatment. The results of the tests and procedures done to diagnosenon-Hodgkin lymphoma are used to help make decisions about treatment.
The following tests and procedures may also be used in the staging
process:
MRI (magnetic
resonance imaging) with gadolinium: A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the brain and spinal cord. A substance called gadolinium is injected into the patient through a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
Lumbar puncture: A procedure used to collect cerebrospinal fluid (CSF) from the spinal column. This is done by placing a needle between two bones in the spine and into the CSF around the spinal cord and removing a sample of the fluid. The sample of CSF is checked under a microscope for signs that the cancer has spread to the brain and spinal cord. This procedure is also called an LP or spinal tap. EnlargeLumbar puncture. A patient lies in a curled position on a table. After a small area on the lower back is numbed, a spinal needle (a long, thin needle) is inserted into the lower part of the spinal column to remove cerebrospinal fluid (CSF, shown in blue). The fluid may be sent to a laboratory for testing.
For pregnant women with non-Hodgkin lymphoma, staging tests and procedures that protect the fetus from the harms of radiation are used. These tests and procedures include MRI (without contrast), lumbar puncture, and ultrasound.
There are three ways that cancer spreads in the body.
Tissue. The cancer spreads from where it began by growing into nearby areas.
Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.
The following stages are used for non-Hodgkin
lymphoma:
Stage I
EnlargeStage I adult lymphoma. Cancer is found in one or more lymph nodes in a group of lymph nodes or, in rare cases, cancer is found in the Waldeyer’s ring, thymus, or spleen. In stage IE (not shown), cancer has spread to one area outside the lymph system.
In stage II, cancer is found in two or more groups of lymph nodes that are either above the diaphragm or below the diaphragm. EnlargeStage II adult lymphoma. Cancer is found in two or more groups of lymph nodes that are either above the diaphragm or below the diaphragm.
In stage IIE, cancer has spread from a group of lymph nodes to a nearby area that is outside the lymph system. Cancer may have spread to other lymph node groups on the same side of the diaphragm.
EnlargeStage IIE adult lymphoma. Cancer has spread from a group of lymph nodes to a nearby area that is outside the lymph system. Cancer may have spread to other lymph node groups on the same side of the diaphragm.
In stage II, the term bulky disease refers to a larger tumor mass. The size of the tumor mass that is referred to as bulky disease varies based on the type of lymphoma.
Stage III
EnlargeStage III adult lymphoma. Cancer is found in groups of lymph nodes both above and below the diaphragm; or in a group of lymph nodes above the diaphragm and in the spleen.
in lymph nodes above the diaphragm and in the spleen.
Stage IV
EnlargeStage IV adult lymphoma. Cancer (a) has spread throughout one or more organs outside the lymph system; or (b) is found in two or more groups of lymph nodes that are either above the diaphragm or below the diaphragm and in one organ that is outside the lymph system and not near the affected lymph nodes; or (c) is found in groups of lymph nodes above the diaphragm and below the diaphragm and in any organ that is outside the lymph system; or (d) is found in the liver, bone marrow, more than one place in the lung, or cerebrospinal fluid (CSF). The cancer has not spread directly into the liver, bone marrow, lung, or CSF from nearby lymph nodes.

is found in the liver, bone marrow, more than one place in the lung, or cerebrospinal fluid (CSF). The cancer has not spread directly into the liver, bone marrow, lung, or CSF from nearby lymph nodes.
Non-Hodgkin lymphomas may be grouped for treatment according to whether the cancer is indolent or aggressive, whether affected lymph nodes are next to each other in the body, and whether the cancer is newly diagnosed or recurrent.
For more information on the types of indolent (slow-growing) and aggressive (fast-growing) non-Hodgkin lymphoma, see the General Information section.
Contiguous lymphomas: Lymphomas in which the lymph nodes with cancer are next
to each other.
Noncontiguous lymphomas: Lymphomas in which the lymph nodes with cancer
are not next to each other, but are on the same side of the
diaphragm.
Non-Hodgkin lymphoma can recur (come back) after it has been treated.
The lymphoma may come back
in the lymph system or in other parts of the body. Indolent lymphoma may come back as
aggressive lymphoma. Aggressive
lymphoma may come back as indolent lymphoma.
Treatment Option Overview
Key Points
There are different types of treatment for patients with non-Hodgkin lymphoma.
Patients with non-Hodgkin lymphoma should have their treatment
planned by a team of healthcare providers who are experts in treating lymphomas.
Treatment for non-Hodgkin lymphoma may cause side effects.
The following types of treatment are used:
Radiation therapy
Chemotherapy
Immunotherapy
Targeted therapy
Plasmapheresis
Watchful waiting
Antibiotic therapy
Surgery
Stem cell transplant
New types of treatment are being tested in clinical
trials.
Vaccine therapy
Patients may want to think about taking part in a clinical trial.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Follow-up tests may be needed.
There are different types of treatment for patients with non-Hodgkin lymphoma.
Different types of treatment are available for patients with non-Hodgkin lymphoma. Some treatments are standard (the currently used treatment), and some
are being tested in clinical trials.
A treatment clinical trial is a research study meant to help
improve current treatments or obtain information on new treatments for patients
with cancer. When clinical trials show that a new treatment is better than the
standard treatment, the new
treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
For pregnant women with non-Hodgkin lymphoma, treatment is carefully chosen to protect the fetus. Treatment decisions are based on the mother’s wishes, the stage of the non-Hodgkin lymphoma, and the trimester of the pregnancy. The treatment plan may change as the signs and symptoms, cancer, and pregnancy change. Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and healthcare team.
Patients with non-Hodgkin lymphoma should have their treatment
planned by a team of healthcare providers who are experts in treating lymphomas.
Treatment will be overseen by a medical
oncologist, a doctor who specializes in treating cancer, or a hematologist, a doctor who specializes in treating blood cancers. The
medical oncologist may refer you to other healthcare providers who have experience and
are experts in treating non-Hodgkin lymphoma and who specialize in certain
areas of medicine. These may include the following specialists:
Side effects from cancer treatment that begin after treatment and continue for months or years are called late effects. Treatment with chemotherapy, radiation therapy, or stem cell transplant for non-Hodgkin lymphoma may increase the risk of late effects.
Late effects of cancer treatment may include the following:
Some late effects may be treated or controlled. It is important to talk with your doctor about the effects cancer treatment can have on you. Regular follow-up to check for late effects is important.
The following types of treatment are used:
Radiation therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing.
Proton beam radiation therapy is a type of high-energy, external radiation therapy that uses streams of protons (tiny particles with a positive charge) to kill tumor cells. This type of treatment can lower the amount of radiation damage to healthy tissue near a tumor such as the heart or breast.
External radiation therapy is used to treat non-Hodgkin lymphoma, and may also be used as palliative therapy to relieve symptoms and improve quality of life.
For a pregnant woman with non-Hodgkin lymphoma, radiation therapy should be given after delivery, if possible, to avoid any risk to the fetus. If treatment is needed right away, the woman may decide to continue the pregnancy and receive radiation therapy. A lead shield is used to cover the pregnant woman's abdomen to help protect the fetus from radiation as much as possible.
EnlargeIntrathecal chemotherapy. Anticancer drugs are injected into the intrathecal space, which is the space that holds the cerebrospinal fluid (CSF, shown in blue). There are two different ways to do this. One way, shown in the top part of the figure, is to inject the drugs into an Ommaya reservoir (a dome-shaped container that is placed under the scalp during surgery; it holds the drugs as they flow through a small tube into the brain). The other way, shown in the bottom part of the figure, is to inject the drugs directly into the CSF in the lower part of the spinal column, after a small area on the lower back is numbed.
When a pregnant woman is treated with chemotherapy for non-Hodgkin lymphoma, the fetus cannot be protected from being exposed to chemotherapy. Some chemotherapy regimens may cause birth defects if given in the first trimester.
Immunotherapy is a treatment that uses the patient’s immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer.
CAR T-cell therapy: The patient's T cells (a type of immune system cell) are changed so they will attack certain proteins on the surface of cancer cells. T cells are taken from the patient and special receptors are added to their surface in the laboratory. The changed cells are called chimeric antigen receptor (CAR) T cells. The CAR T cells are grown in the laboratory and given to the patient by infusion. The CAR T cells multiply in the patient's blood and attack cancer cells. CAR T-cell therapy (such as axicabtagene ciloleucel or tisagenlecleucel) is used to treat large B-cell lymphoma that has not responded to treatment. CAR T-cell therapy is being studied to treat mantle cell lymphoma that has relapsed or not responded to treatment.
EnlargeCAR T-cell therapy. A type of treatment in which a patient’s T cells (a type of immune cell) are changed in the laboratory so they will bind to cancer cells and kill them. Blood from a vein in the patient’s arm flows through a tube to an apheresis machine (not shown), which removes the white blood cells, including the T cells, and sends the rest of the blood back to the patient. Then, the gene for a special receptor called a chimeric antigen receptor (CAR) is inserted into the T cells in the laboratory. Millions of the CAR T cells are grown in the laboratory and then given to the patient by infusion. The CAR T cells are able to bind to an antigen on the cancer cells and kill them.
Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells. Monoclonal
antibodytherapy, proteasome inhibitor therapy, and kinase inhibitor therapy are types of targeted therapy used to treat non-Hodgkin lymphoma.
Monoclonal
antibody therapy: Monoclonal antibodies are immune system proteins made in the laboratory to treat many diseases, including cancer. As a cancer treatment, these antibodies can attach to a specific target on cancer cells or other cells that may help cancer cells grow. The antibodies are able to then kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells.
Types of monoclonal antibodies include:
Rituximab, used to treat many types of non-Hodgkin lymphoma.
Brentuximab vedotin, which contains a monoclonal antibody that binds to a protein called CD30 that is found on some lymphoma cells. It also contains an anticancer drug that may help kill cancer cells.
Mosunetuzumab, which is a bispecific monoclonal antibody that helps the body's immune system recognize and kill cancer cells. It is used to treat relapsed or refractory follicular lymphoma.
How do monoclonal antibodies work to treat cancer? This video shows how monoclonal antibodies, such as trastuzumab, pembrolizumab, and rituximab, block molecules cancer cells need to grow, flag cancer cells for destruction by the body’s immune system, or deliver harmful substances to cancer cells.
Proteasome inhibitor therapy: This treatment blocks the action of proteasomes in cancer cells. Proteasomes remove proteins no longer needed by the cell. When the proteasomes are blocked, the proteins build up in the cell and may cause the cancer cell to die. Bortezomib or ixazomib is used to decrease how much immunoglobulin M is in the blood after cancer treatment for lymphoplasmacytic lymphoma (Waldenström macroglobulinemia). It is also being studied to treat relapsedmantle cell lymphoma.
Kinase inhibitor therapy: This treatment blocks certain proteins, which may help keep lymphoma cells from growing and may kill them. Kinase inhibitor therapies include:
Ibrutinib, acalabrutinib, and zanubrutinib, which are types of Bruton tyrosine kinase inhibitor therapy. They are used to treat mantle cell lymphoma. Ibrutinib and acalabrutinib are also used to treat lymphoplasmacytic lymphoma, and zanubrutinib is being studied to treat it.
Histone methyltransferase inhibitor therapy: Tazemetostat is used to treat follicular lymphoma that has come back or has not gotten better with other treatment. It is used in adults whose cancer has a certain mutation (change) in the EZH2 gene that has already been treated with at least two other anticancer therapies.
B-cell lymphoma-2 (BCL-2) inhibitor therapy: Venetoclax may be used to treat mantle cell lymphoma. It blocks the action of a protein called BCL-2 and may help kill cancer cells.
If the blood becomes thick with extra antibody proteins and affects circulation, plasmapheresis is done to remove extra plasma and antibody proteins from the blood. In this procedure, blood is removed from the patient and sent through a machine that separates the plasma (the liquid part of the blood) from the blood cells. The patient's plasma contains the unneeded antibodies and is not returned to the patient. The normal blood cells are returned to the bloodstream along with donated plasma or a plasma replacement. Plasmapheresis does not keep new antibodies from forming.
Small bowel surgery is often needed to diagnoseceliac disease in adults who develop a type of T-cell lymphoma.
Stem cell transplant
Stem cell transplant is a method of giving high doses of chemotherapy and/or total-body irradiation and then replacing blood-forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient (autologous transplant) or a donor (allogeneic transplant) and are frozen and stored. After the chemotherapy and/or radiation therapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body’s blood cells.
EnlargeDonor stem cell transplant. (Step 1): Four to five days before donor stem cell collection, the donor receives a medicine to increase the number of stem cells circulating through their bloodstream (not shown). The blood-forming stem cells are then collected from the donor through a large vein in their arm. The blood flows through an apheresis machine that removes the stem cells. The rest of the blood is returned to the donor through a vein in their other arm. (Step 2): The patient receives chemotherapy to kill cancer cells and prepare their body for the donor stem cells. The patient may also receive radiation therapy (not shown). (Step 3): The patient receives an infusion of the donor stem cells.
New types of treatment are being tested in clinical
trials.
This summary section describes treatments that are being studied in
clinical trials. It may not mention every new treatment being studied.
Information about clinical trials is available from the
NCI website.
Vaccine therapy
Vaccine therapy is a cancer treatment that uses a substance or group of substances to stimulate the immune system to find the tumor and kill it.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Clinical trials are taking place in many parts of the country. Information about clinical trials supported by NCI can be found on NCI’s clinical trials search webpage. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.
Follow-up tests may be needed.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
If the tumor is too large to be treated with radiation therapy, the treatment options for indolent, noncontiguousstage II, III, or IV
non-Hodgkin lymphoma will be used.
Treatment of indolent, noncontiguous stage II, III, or IV non-Hodgkin lymphoma may include the following:
Watchful waiting for patients who do not have signs or
symptoms.
Monoclonal
antibody therapy (rituximab) with or without chemotherapy.
For extragastric MALT lymphoma of the eye and Mediterranean abdominallymphoma, antibiotic therapy is used to treat infection.
For splenicmarginal zone lymphoma, rituximab with or without chemotherapy and B-cell receptor therapy is used as initial treatment. If the tumor does not respond to treatment, a splenectomy may be done.
For mantle cell lymphoma, monoclonal antibody therapy with combination chemotherapy, followed by stem cell transplant. Monoclonal antibody therapy may be given afterwards as maintenance therapy (treatment that is given after initial therapy to help keep cancer from coming back).
Polatuzumab vedotin, combined with bendamustine and rituximab.
A clinical trial of autologous or allogeneic stem cell transplant.
Treatment of indolent
lymphoma that comes back as aggressive lymphoma depends on the type of non-Hodgkin lymphoma and may include radiation therapy as palliative therapy to relieve symptoms and improve quality of life. Treatment of aggressive lymphoma that comes back as indolent lymphoma may include chemotherapy.
Treatment of Non-Hodgkin Lymphoma During Pregnancy
Treatment given right away based on the type of non-Hodgkin lymphoma to increase the mother's chance of survival. Treatment may include combination chemotherapy and rituximab.
Early delivery of the baby followed by treatment based on the type of non-Hodgkin lymphoma.
If in the first trimester of pregnancy, medical oncologists may advise ending the pregnancy so that treatment may begin. Treatment depends on the type of non-Hodgkin lymphoma.
